Development of IVIVC In vitro release (Dissolution at multiple pH and agitations) Administration to healthy volunteers (Crossover design) Design of MR Formulations IVIVC Deconvolution (Absorption)
Practical Application: In Vivo and In Vitro Data Required In Vivo Data – Bioavailability Studies At least 2 test formulations with different release rates (3 or more recommended) Solution, immediate release, or IV reference (unit impulse response) Crossover studies in fasted subjects Parallel studies acceptable (common treatment across studies) In Vitro Data – Dissolution Studies Test formulations should exhibit at least 10% difference in dissolution USP apparatus I (basket @ 100 rpm) or II (paddle @ 50 rpm) preferred Adjust dissolution conditions to fit in vivo data/obtain proper discrimination If dissolution is faster or slower than in vivo absorption, adjust the time scale
